Alstroemeria plant named &#39;Zapriliali&#39;

ABSTRACT

A new and distinct cultivar of  Alstroemeria  plant named ‘Zapriliali’, characterized by its compact, upright to outwardly spreading and uniformly mounded plant habit; vigorous growth habit; rapid growth rate; numerous light pink-colored flowers with greyed purple-colored stripes on the inner perianth segments; and excellent container and garden performance.

Botanical designation: Alstroemeria hybrida.

Cultivar denomination: ‘ZAPRILIALI’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Alstroemeria plant, botanically known as Alstroemeria hybrida, commercially used as a potted and garden-type Alstroemeria plant and hereinafter referred to by the name ‘Zapriliali’.

The new Alstroemeria plant is a product of a planned breeding program conducted by the Inventor in Rijsenhout, The Netherlands. The objective of the breeding program is to create new potted Alstroemeria plants with uniform plant habit, freely flowering habit, attractive leaf and flower coloration and good garden performance.

The new Alstroemeria plant is a naturally-occurring whole plant mutation of Alstroemeria hybrida ‘Zaprielia’, disclosed in U.S. Plant Pat. No. 22,338. The new Alstroemeria plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘Zaprielia’ in a controlled greenhouse environment in Rijsenhout, The Netherlands in March, 2011.

Asexual reproduction of the new Alstroemeria plant by rhizome divisions in a controlled greenhouse environment in Rijsenhout, The Netherlands since June, 2011 has shown that the unique features of this new Alstroemeria plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Alstroemeria have not been observed under all possible combinations of environmental conditions and cultural conditions. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Zapriliali’. These characteristics in combination distinguish ‘Zapriliali’ as a new and distinct potted Alstroemeria plant:

-   -   1. Compact, upright to outwardly spreading and uniformly mounded         plant habit.     -   2. Vigorous growth habit and rapid growth rate.     -   3. Numerous light pink-colored flowers with greyed         purple-colored stripes on the inner perianth segments.     -   4. Excellent container and garden performance.

Plants of the new Alstroemeria differ primarily from plants of the mutation parent, ‘Zaprielia’ in flower color as plants of ‘Zaprielia’ have dark pink-colored flowers. In addition, plants of the new Alstroemeria are taller than plants of ‘Zaprielia’.

Plants of the new Alstroemeria can be compared to plants of Alstroemeria hybrida ‘Zapriliarange’, disclosed in a U.S. Plant patent application filed concurrently. In side-by-side comparisons, plants of the new Alstroemeria differ primarily from plants of ‘Zapriliarange’ in flower color as plants of ‘Zapriliarange’ have orange-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Alstroemeria plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Alstroemeria plant.

The photograph on the first sheet is a side perspective view of a typical flowering plant of ‘Zapriliali’ grown in a container.

The photograph on the second sheet is a close-up view of a typical flowering plant of ‘Zapriliali’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants of the new Alstroemeria grown during the late winter and early spring in 14-cm containers in a glass-covered greenhouse in Rijsenhout, The Netherlands. During the production of the plants, day temperatures ranged from 15° C. to 25° C., night temperatures ranged from 10° C. to 15° C., soil temperature averaged 14° C. and minimum light levels were 5,000 lux. Plants were three months old when the photographs and the description were taken.
